It's been nearly a month since 'Glee' star Becca Tobin lost her boyfriend, Matt Bendik, to an unknown cause. But the 28-year-old Georgia native finally opened up to her fans on Instagram and thanked everyone for their support.

"Thank you all for the love and support," she wrote in an Instagram post, along with a photo of her and her late boyfriend. "Matt was the most extraordinary man I knew and he will live in my heart forever."

On July 10, Bendik's body was discovered in a Philadelphia hotel by a maid. Bendik, a 35-year-old nightclub promoter, had been visiting the Philadelphia area on business. The cause of Bendik's death remains unclear, although previous reports suggested that stress-related issues may have played a part. There was no evidence of foul play, alcohol poisoning or drug overdose at the time.

Tobin joined the cast of 'Glee' in Season 4 and was promoted to a series regular for Season 5.

Season 6 of 'Glee' will air in early 2015. Series creator Ryan Murphy has already confirmed that it will be the show's final season.
